I have a 40 yr old fir tree about 2 ft tall, for last few years there is formation of nodules on all the branches , and there is almost no new growth every year, I need help on how to treat this problem, so far there has been very little dying of the branches.the nodules are about 1/2 inch in diameter, soft pulpy centers, not much pitch inside
